Introduction: Should You Register for VAT?
If your business turnover is creeping up — or has already shot past a certain point — you’ve probably started asking yourself whether you need to register for VAT. It’s one of those admin tasks that sounds complicated but, once you understand the rules, is genuinely manageable.
The honest answer is: it depends on your turnover, your customers, and your ambitions for the business. Some small business owners register for VAT voluntarily before they’re legally required to. Others wait until they have no choice. A few use special schemes to simplify the whole process.
This guide walks you through everything you need to know about VAT registration as a UK small business owner or sole trader in 2026 — from the compulsory threshold to voluntary registration, the Flat Rate Scheme, and how to stay on the right side of HMRC without losing your mind.
What Is the VAT Registration Threshold in 2026?
The VAT registration threshold in 2026 is £90,000. This was increased from £85,000 in April 2024 and has remained at £90,000 going into 2026.
If your taxable turnover exceeds £90,000 in any rolling 12-month period, you are legally required to register for VAT with HMRC. Note: this is a rolling 12-month period, not a tax year. So you need to be monitoring your turnover month by month, not just at the end of April each year.
There’s also a forward-looking rule: if you expect your taxable turnover to exceed £90,000 in the next 30 days alone, you must register immediately — even if you haven’t actually crossed the threshold yet.
What Counts as Taxable Turnover?
Taxable turnover includes sales of goods and services that are subject to VAT at any rate — including the standard rate (20%), the reduced rate (5%), and the zero rate (0%). It does not include VAT-exempt sales (such as certain financial services, insurance, or private education).
If you’re not sure whether your products or services are taxable, HMRC’s guidance on VAT rates is the best starting point, or consult an accountant who knows your industry.
When Do You Need to Register?
You need to register for VAT when:
- Your taxable turnover in the last 12 months has exceeded £90,000, or
- You expect your taxable turnover to exceed £90,000 in the next 30 days
Once you’ve hit the threshold, you have 30 days to register. HMRC will then confirm your VAT registration number and effective date of registration.
Missing this deadline can result in a penalty, so it’s worth setting up a simple spreadsheet or using your accounting software to track rolling 12-month revenue.
What Happens After You Register?
Once registered, you’ll need to:
- Charge VAT on your taxable sales (usually at 20%)
- Submit VAT returns — typically quarterly — to HMRC
- Keep digital VAT records under Making Tax Digital (MTD) for VAT
- Pay any VAT owed to HMRC by the relevant deadlines
Making Tax Digital for VAT has been mandatory for all VAT-registered businesses since April 2022, regardless of turnover. This means you must use compatible accounting software to keep your records and submit your VAT returns. You cannot simply fill in a spreadsheet and post it to HMRC.
Popular MTD-compatible software used by UK small businesses includes QuickBooks, Xero, Sage, and FreeAgent. Many have free trials, and FreeAgent is available free of charge through certain NatWest or Royal Bank of Scotland business accounts.
Voluntary VAT Registration: Is It Worth It?
Here’s something that surprises many new business owners: you don’t have to wait until you hit £90,000 to register for VAT. You can register voluntarily at any turnover level.
Reasons to Register Voluntarily
You sell mainly to VAT-registered businesses. If most of your customers are businesses (rather than members of the public), they can reclaim any VAT you charge them. This means being VAT-registered makes little difference to what they actually pay — but it allows you to reclaim VAT on your own business purchases. If you’re spending heavily on equipment, materials, or software, this can be a meaningful saving.
You want to appear more established. Rightly or wrongly, some clients assume that a business with a VAT number is more credible or larger than one without. If you’re targeting corporate clients, a VAT number can help with that perception.
You’re approaching the threshold. If you’re at, say, £75,000–£80,000 turnover and growing steadily, voluntary registration now means you can plan your pricing and admin calmly — rather than scrambling to register mid-contract when you suddenly tip over £90,000.
Reasons Not to Register Voluntarily
You sell mainly to consumers or small non-VAT-registered businesses. If your customers can’t reclaim VAT, then registering means either your prices go up by 20% (making you less competitive) or you absorb the VAT yourself (cutting your margin). Neither is great.
Your admin burden increases. VAT returns, MTD-compatible software, keeping records — it all takes time or money. If you’re a sole trader with a tight schedule and modest turnover, adding that overhead might not be worth it.
The VAT Flat Rate Scheme: A Simpler Option for Small Businesses
If your VAT-inclusive taxable turnover is £150,000 or less, you may be eligible to join HMRC’s Flat Rate Scheme (FRS). This is one of the most underused tools available to small businesses, and it can genuinely simplify your life — though it doesn’t always save money, and there’s an important catch for many service businesses.
How the Flat Rate Scheme Works
Under the standard VAT scheme, you charge 20% VAT on your sales, reclaim VAT on your purchases, and pay HMRC the difference. Under the Flat Rate Scheme, it’s different:
- You still charge your customers the standard rate of VAT (usually 20%)
- But you pay HMRC a fixed percentage of your gross turnover — the percentage depends on your business sector
- You generally cannot reclaim VAT on purchases (with one exception: single capital asset purchases over £2,000 including VAT)
The flat rate percentages vary by sector — from around 4% (for retailers of food, confectionery, newspapers) to 14.5% (for IT and consultancy businesses, for example). HMRC’s website has the full current list.
The Limited Cost Trader Rate — Important for Service Businesses
If you spend less than 2% of your VAT-inclusive turnover on goods (or less than £1,000 per year on goods), HMRC classifies you as a “limited cost trader” and applies a flat rate of 16.5% — regardless of your sector. This effectively eliminates most of the financial benefit of the FRS for pure service businesses (consultants, copywriters, coaches, web developers, and similar). Before joining the FRS, calculate whether the limited cost trader rate applies to you — it’s a common reason the scheme turns out not to be the money-saver it appears.
When the Flat Rate Scheme Saves You Money
The FRS can save you money when the flat rate percentage for your sector (or the limited cost trader rate, if it applies) is lower than your actual effective VAT rate. For example, if you’re a food retailer whose flat rate is 4% but you’d effectively pay more under the standard scheme, you keep the difference.
In your first year of VAT registration, HMRC gives you a 1% discount on your flat rate, which improves the economics further.
When It Doesn’t Work in Your Favour
If you have high input VAT costs — meaning you buy lots of goods or services with VAT on them — the standard scheme will likely serve you better, because you can reclaim all that input tax. The FRS is most beneficial for product businesses with a sector rate well below 20%, or for businesses where the admin simplicity justifies the trade-off.
How to Register for VAT with HMRC
Registering is straightforward and done entirely online:
- Create or log in to your HMRC Government Gateway account
- Complete the VAT registration form (VAT1) — you’ll provide details about your business, turnover, and trading activity
- Choose your VAT scheme — standard accounting, cash accounting, annual accounting, or Flat Rate Scheme
- Submit — HMRC typically processes applications within 10 working days, though it can take longer at busy periods
Once registered, you’ll receive a VAT registration certificate showing your VAT number and the date from which you must charge VAT. Keep this safe.
Common Mistakes to Avoid
- Not monitoring turnover on a rolling basis. Set a monthly reminder to check your last 12 months’ taxable turnover.
- Forgetting to charge VAT from your effective date of registration. You’re liable for VAT from that date, even if your certificate hasn’t arrived yet.
- Mixing up VAT-exempt and zero-rated supplies. Zero-rated supplies still count towards your taxable turnover; exempt supplies do not. Get this wrong and you may under-report your threshold position.
- Not using MTD-compatible software. HMRC requires digital record-keeping — a manual spreadsheet is not sufficient.
- Assuming the Flat Rate Scheme always saves money. Check whether the limited cost trader rate (16.5%) applies to you before signing up.
FAQ
Do I need to register for VAT if I’m a sole trader? Yes, if your taxable turnover exceeds £90,000 in a rolling 12-month period, you must register regardless of your business structure — whether you’re a sole trader, limited company, or partnership. The threshold applies to the business, not to the legal entity type.
Can I deregister for VAT if my turnover drops? Yes. You can apply to deregister if your taxable turnover is expected to fall below the deregistration threshold, which is currently £88,000. Note that this is lower than the registration threshold, which prevents businesses from constantly registering and deregistering as turnover fluctuates around the £90,000 mark.
How do I reclaim VAT I paid before I registered? You can reclaim VAT on goods purchased up to 4 years before your registration date (as long as you still have those goods), and on services purchased up to 6 months before registration. You’ll do this on your first VAT return. Keep all your invoices.
What software do I need to comply with Making Tax Digital for VAT? You need MTD-compatible accounting software to keep your VAT records digitally and submit returns directly to HMRC. Popular choices for UK small businesses include QuickBooks, Xero, Sage Accounting, and FreeAgent. Pricing varies — check our software comparison section for current details and deals, as several providers offer free trials.
Conclusion: What Should You Do Next?
If your turnover is approaching or has passed £90,000, register now — don’t wait and risk a penalty. Set up MTD-compatible accounting software before you register so you’re ready from day one.
If you’re below the threshold, take an honest look at your customer base. If you sell mainly to other VAT-registered businesses and you have meaningful input VAT costs, voluntary registration could work in your favour. If your customers are mostly consumers or small non-VAT-registered buyers, there’s generally no rush.
And if you’re eligible, consider the Flat Rate Scheme — but do the maths first. Check whether the limited cost trader rate (16.5%) applies to your situation, and compare it against what you’d pay under the standard scheme. If the numbers work, the admin simplicity can make it worthwhile, especially with the extra 1% discount in your first year.
When in doubt, spend an hour with a good accountant who understands your sector. The cost of that conversation is almost always worth it.
